re plumbing question

[ECFENCING]

I plan on placing a sump in my basement and had a question about which pump would work best and what size pvc I should use.

The sump will be located in the basement for a total run of approx 20 feet. The return is 3/4" and the drain is 1". The tank is a 92 AGA corner.

Specifically I was thinking of using the following pump:

Gen-X PCX-40 1140 gph Water PumpThe Gen-X PCX-40 magnetic drive water pump. 3/4" MNPT Inlet/Outlet. Maximum flow-1190GPH/[email protected]' Pressure rated for a maximum lift of 22ft. Economical to run-1.2amps,110Volts Power consumption 110watts. Quiet, cool running, no oiling required. 1 year against manufacturer defects.

Does anyone out there have any suggestions for plumbing a run of approx 20 feet ?


Also should I start out with 1" flex pvc and increase to 2" flex for the drain and start out with 1" pvc and decrease to 3/4" for the return or should I just go with staying with the same diameter?

Thinking of using a rubbermaid 100g stock tank for the sump with no baffles.

Any quick response would be greatly appreciated as I plan on doing this next week and I have someone coming over to help me out.

Thanks.

That pump won't cut it. That pump is only good for about 22 feet and you have roughly 20. Add in a few bends, a ball valve etc, and you're past 22 head feet. Also even at 20 head feet of pressure the volume it can pump will be very low.

I'd look into pressurized pumps. I was looking into the Sequence UNO series.

Ernie, how many feet of vertical lift are you working with? 20' of pipe doesn't necessarily convert to 20' of head pressure.

If you've got 8'-10' of vertical and the rest is a horizontal run, then you might be ok with the Gen-X5 - PCX100.

The info you provided doesn't offer enough to make the determination whether or not the pump is adequate.

Thanks. Total vertical lift is about 11 feet I'll post a diagram shortly

Uploaded diagram. Don't have visio so it's not the best.

I use an Iwaki 70RLT which works pretty well but I tee off to a refugium and dial down the overall pressure with a ball valve.

you need something similar to this. you can't drain more than 600gal/h so this pump at that head pressure will get you close to what you can handle. you can always by something bigger and valve it down. look at flow vs head charts and find something more then 500-600gal/h and you should be fine.

which the pump you are looking at are but i have had one and mine was very noise but if you aren't in you basement then your fine.

Ernie, I see minimum of 15' of head pressure. I get this figure as follows:

12' vertical rise
1' 90 deg above sump
1' 90 deg from the horizontal to go up through floor
1' 90 deg going into the tank

That's 15'. However, there is additional head pressure if you're using a ball valve, union, and the pipe/tubing itself. I am also not sure if I've got all the 90's that you'll be using calculated into the above equation. Each one of these listed 'appliances' & fittings adds one foot of head pressure to the total.

The pump drunk linked could be a viable choice. Let's say you've got ~ 18'-19' of head pressure, then the Iwaki 40rt would yield approx. 360 gph. Low in my opinion.

However, the Iwaki 55RLT could yield about 600 gph at 19'.

Hope this helps.

Russ: Thanks. I used reefcentrals head loss calculator and the iwaki 55rlt resulted in approx 590gph and around 18' of head pressure.

Ernie,

When I setup the sump in the garage, I had a 15' horizontal run and a 5 1/2' vertical. I used the Velocity T4 and had great flow. That pump was rated 1225 gph @ 3'. Is there anyway you can move the sump directly under the tank and just make it a straight vertical lift? BTW, sump in the basement is def. the way to go.

i used to have an Iwaki MD70RLXT at 20 ft in a 92 corner n still wasn't enough.
if noise is not a factor, its always better to get a more powerful pump than u think u need.

I wish I could place it directly under the tank and make it a straight vertical lift but that is the part of the basement that is semi-finished and it would be an eyesore to have it in that location.

Wish there was an easier way.
